AMMI M. GEORGE, OF NASHUA., NEW HAMPSHIRE.

IMPROVEMENT IN PIPE-COUPLINGS.

To all whom 'it may concern:

Beit known that I, AMMI M. GEORGE, of Nashua, in the county oi' Hillsborough and State of New Hampshire, have invented a new and l Improved Hose-Coupling; and I do hereby dethe heads, projections, or buttons to other positions while thetwo parts of the coupling are together the coupling is bound together and iirmly held.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and use.

In the drawings, Figure 1 is a perspective \'iew,showingthe two partsA andCofthecoupling together, and the same locked by the button-bolts B B'. Fig. 2 is aplan of that part of the coupling represented by A in Fig. 1, showing the. buttons, heads, or projections b b' ot' the bolts B B' so turned as to coincide in direction with the holes h h, Fig. 3, provided for them. Fig. 3 is a plan ofthat part ofthe coupling represented by C in Fig. 1. Fig. 4 is a section through that part of the coupling represented by A in Fig. 1, showing by section the button-bolts B B'. Fig. 5 is a section through that part of coupling represented by C in Fig. 1. Fig. 6 represents a perspective view of one ofthe bolts,B beingthe principal part orbody of the bolt, and b the button, head, or projection. d, a part of the bolt which I call the shank, is turned smaller, so as to give a shoulder to the bolt for the purpose of preventing it from passing farther through the iiange of the coupling (see Fig. 4) than is desired. r is a ring to be'fastened to the shank dby means of the pin p, for the purpose of holding the bolt B in position. Fig. 7 is a section and view representing the part that would be cut off by a line', S T, through that part of the coupling represented by Fig. 3. k 7c' l Z', is an inclined plane sloping upward from the hole in the iiange of the part C. This is also shown in Figs.3 and S. Fig. 8 is a section of the part represented by Fig. 7; Fig. 9, a modified form of the headL of the button-bolt; Fig. 10, a view of wrench for turning the bolts.

The coupling is made of any suitable metal, in two parts, as shown in Fig. 1. The partA is shown in section in Fig. 4, and has an enlarged recess, ij, Figs. 2 and 4, turned into it for the purpose of receiving and for forming a socket for the projection i'j', Fig. 5, ofthe part C. P, in Fig. 4, are rubber rings for packing.

The bolt B, Fig. 6, is made of any suitable metal, and may be ot' the exact shape shown, or in any other form that shall retain the principle. Instead of one projection to form the 'head,thebolt may have two, as shown in Fig. 9.

lnclines 7c 7c' l l', lc 7s' l Z', as shown in Fig. 3,

aremadeadjoiningthebolt-holes. Theirshape and position will bc readily understood by inspection of drawings 3 and 7.

The use ot' the coupling is this: Wewll suppose the two parts ofthe coupling are attached to the hose which wewish to unite. Now turn the button-bolts B B' so that the projections, buttons, or heads b b' shall stand in such a position as to allow the two parts ot' the'couplin g to be put together. This being accomplished, turn the heads, buttons, or projections b b' ot the boltsso that they may come to a bearing on the inclines 7c la' l l', kk l l', and thus draw the two parts ofthe coupling together and hold them firmly in position, thus connecting thc hose.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the projections, heads, or buttons b b' of the bolts B B', and the iuclinedsurfaces 7c lc' l l', 7c 7c' l l', with the two parts of the coupling, substantially as and for the purpose set forth.
